And while you thus pray daily for yourselves, it is your privilege and duty to include in your petitions all with whom you are connected in the various relations of life. You ought to pray continually for your beloved father, who is engaged in such important labour for the Church, and who loves you with an affection and solicitude which you can never repay; for your grandparents, who are daily praying for you, and who are falling more and more under the infirmities of age; for one another, that you may be guided and blessed amidst all the temptations and dangers of youth; for your teachers; for your school-mates; for the poor children around you, who have none of the advantages of instruction and restraint which you enjoy; for your friends, and neighbours, and all with whom you are acquainted. O, my dear children, if you prayed as you ought every day for all these, how much happier would you be! What a benign influence it would have on your whole temper and conduct! It would make you kind, tender hearted, and forgiving toward all with whom you conversed; and make all of them, in their turn, love you as a friend and benefactor.

Let me make, on this subject, one more suggestion. Most people, especially most young people, have no idea of engaging in prayer unless at particular times when they retire for the purpose. I wish you all, dear children, besides your stated seasons of prayer, morning and evening, to form the habit of lifting up your thoughts and your desires to God in any and every situation; when walking by the way; when surrounded with company; when met by any call of duty, or by any circumstance of a doubtful aspect, or perplexing character—be in the habit of silently but devoutly looking up to God for wisdom and strength to perform every duty. This kind of intercourse with God may be carried on at all times, and in all situations; and, I will add, was never sincerely adopted by any one without being connected with guidance and consolations of unspeakable value. In this way the suggestion of the apostle in writing to Timothy will be realized, that "every thing be sanctified by the word of God, and prayer."

LETTER VI.
CULTIVATION OF THE MIND.

Dear Children:—That every human being is bound to cultivate, in the best manner, the intellectual powers which God has given him, I hope you will take for granted, anterior to all argument; and, although the moral aspects of education are the most vitally important, yet as no one can be a moral agent without some degree of intellect; so it may be said, that the wisest and best culture even of our moral powers, depends more on the discipline, the enlargement, and the furniture of the intellect, than is commonly supposed.

The cultivation of the mind comprises two things, and two only, viz: giving it proper habits of exercise, and filling it with useful knowledge. The case is precisely similar with regard to the body. The sum total of all that we are called to do for the benefit of the body, is to secure its strength by constant and wholesome action or exercise, and to furnish it with appropriate nourishment. On the one hand, were its exercise ever so abundant, if left without aliment, it would speedily sink into weakness and death; and, on the other, if its aliment be ever so plentiful and rich, yet if it be left wholly without exercise, it will soon become a mass of disease and corruption. Precisely so is it in the cultivation of the mind. Exercise and aliment are equally indispensable, and must go together. If the mind be not taught to think, and to feel an appetite for intellectual provision, all the knowledge in the world, if introduced into it, would be of little use. But, if it be taught only to think and feel, and be furnished with none of the appropriate aliment of knowledge, it cannot grow either in strength, or in a capacity to act its part in the world with dignity or usefulness.

As these principles lie at the foundation of all intellectual culture, so they are also adapted to instruct us with regard to the wisest and best means of conducting that culture, with regard to the departments of knowledge most worthy of being studied, and the relative stress which ought to be laid on different pursuits. If you would be trained up merely to be splendid butterflies, to shine and to please the superficial and the empty, for a day, and, having done this, to die like senseless insects; why, then, a corresponding plan of culture must be adopted. But, if you wish to be regarded as rational creatures; to be prepared for sober thought and action; to "serve your generation by the will of God;" to die in peace, and to be remembered with love and veneration when you are gone, then it is perfectly manifest a very different method of training is indispensable.

I trust you will not hesitate a moment in deciding which of these courses you ought to choose. I trust the way of practical wisdom, of piety, and of usefulness, will be the object of your prompt and decisive choice. If so, the course of mental culture which you ought to adopt, cannot possibly be mistaken by a mind of the least reflection. If you are to feel and act as moral accountable agents, and to consider human life as a serious, momentous thing; then, doubtless, you will feel that you are bound, first of all, and above all, to exercise your minds in such a manner, and to store them with such branches of knowledge, as will tend most effectually to enlarge them, to strengthen them, to inspire them with practical wisdom, and to furnish them with the means of the most solid and extensive usefulness.

Upon this principle, I would say, let your first and chief attention be directed to those branches of knowledge which lie at the foundation of all that is enlarged, liberal, and elevated in human pursuits; such as Grammar, Rhetoric, Geography, the Latin, Greek, and French languages, Natural and Moral Philosophy, the elements of Mathematical science, Chemistry, and as many of the branches of Natural History as may be within your reach, especially Botany and Mineralogy. These are all proper for both sexes; and the more you gain of all of them, the better fitted will you be both for enjoying life, and for fulfilling its various and momentous duties. I grant, indeed, my dear grandson, that with regard to what is denominated Classic literature, and Mathematics, I wish you to go more thoroughly to work, than would be desirable, or perhaps proper, for your sisters. But I hope that neither of these will be entirely neglected by them. For I have an impression, that the careful study, to a certain extent, of the best of the dead languages, and an intelligent acquaintance with the elementary principles of Mathematics, ought to be omitted by none who can possibly attain them. In my opinion, they are adapted to produce an effect on the mind, and to diffuse an influence over all its other acquisitions, more happy and more important than is commonly recognised, even by many of the educated themselves.
